Development Status:

With the rapid development of smart phones, simple hardware upgrades can no longer meet the needs of users, and it is impossible to activate the market in depth during the stock competition period, and the products have begun to enter the stage of exploring micro-innovation.

Hello, this is that you have turned on the automatic brightness, when the phone senses that the scene is dark, he will increase the brightness, and the scene will be darkened when the scene is bright, thank you.

The phone will be on and off, and it can be caused by several factors. On the one hand, this may be due to the phone's adaptive screen brightness feature. Phone Adaptive Brightness is an automatic brightness adjustment feature based on ambient light, which can adjust the brightness of the screen by detecting the brightness level of the surrounding environment through the phone's built-in light-sensitive sensor.

Therefore, when the brightness around you changes, the brightness of your phone's screen also changes, resulting in the screen being bright and dark.

On the other hand, the phone will light up and darken the bright key core may also be due to the influence of the phone's battery life. As the battery continues to be used, the battery capacity and health will gradually decay, which may lead to the problem of unstable battery discharge when the phone is in use. In this case, the phone's screen may flicker and change brightness due to insufficient remaining power.

In addition, it can also be due to a malfunction of the system or application that the phone will turn on and off. When the system or application excites the sequence, it can cause the screen to flicker and change brightness. In this case, you can try to fix the problem by restarting your phone, clearing the app cache, or uninstalling recently installed apps.

In conclusion, the fact that a phone turns on and off can be due to a number of factors, including the ability to adapt to the screen brightness, battery life, system or app failures, etc. If this happens frequently, the user can try to optimize the brightness settings, replace the battery, or upgrade the system to resolve the issue. <>
